The standard 232 bar fitting does not screw all the way into a 300 bar bottle so you have to either machine approximately 2.5mm off the shoulder on the brass adapter or do as many do and use 2 off 8mm washers in the bottom of the hole which will space the adapter out enough to fit on a 300bar bottle. As you will only be charging the gun to 200 bar you should have no problems. Don't charge any higher than 200 bar though.
